You can use the i.mx6D based on your tests. For the i.mx6DL, note that it has half as much L2 cache (512KB instead of 1MB) Also, max ddr speed for i.mx6DL is 400 MHz vs 533 MHz for i.mx6D. So if you can tune the cache params and the DDR speed on your i.mx6Q and re-run your tests, this will give you a better confidence on going with the i.mx6DL. I would be interested in your results. Thanks
